➤ Answer :-

${\tt \longrightarrow \dfrac{9}{11} - \dfrac{4}{15}}$

Convert them into like fractions by taking the LCM of the denominators i.e, 11 and 15.

LCM of 11 and 15 is 165.

${\tt \longrightarrow \dfrac{9 \times 15}{11 \times 15} - \dfrac{4 \times 11}{15 \times 11}}$

${\tt \longrightarrow \dfrac{135}{165} - \dfrac{44}{165} = \dfrac{135 - 44}{165}}$

$\tt \longrightarrow \dfrac{91}{165}$

$\Huge\therefore$The answer is ${\tt\dfrac{91}{165}}$.

${\tt \longrightarrow \dfrac{7}{10} + \dfrac{2}{5} + \dfrac{3}{2}}$

Convert them into like fractions by taking the LCM of the denominators i.e, 10,5 and 2.

LCM of 10,5 and 2 is 10.

${\tt \longrightarrow \dfrac{7}{10} + \dfrac{2 \times 2}{5 \times 2} + \dfrac{3 \times 5}{2 \times 5}}$

${\tt \longrightarrow \dfrac{7}{10} + \dfrac{4}{10} + \dfrac{15}{10}}$

$\tt \longrightarrow \dfrac{7 + 4 + 15}{10} = \dfrac{26}{10} = \boxed{ \tt 2 \dfrac{6}{10}}$

$\Huge\therefore$The answer is $\tt 2 \dfrac{6}{10}$

More to know...............

• While adding or subtracting the fractions, if the given fractions are having different denominators i.e, if they are unlike fractions, we should convert them into like fractions by taking the LCM of the denominators.
• While adding or subtracting the fractions, if the given fractions are having same denominators i.e, if thet are like fractions, we can add or subtract them easily by looking into numerators.
